Update / Set plugin custom field (checklist) value

[Tim Yeung]

I want to ask how do you update plugin custom field value programatically, in particular, custom field provided by an external plugin.

I am using the checklist custom field (https://marketplace.atlassian.com/plugins/com.okapya.jira.checklist), and I want to make a workflow post function that check one of the checklist option in my plugin.

The problem is that, for a normal native JIRA custom field, such as text, it is pretty simple (mutableIssue.setCustomFieldValue(customField, "SimpleText")), but since the checklist custom field value uses classes inside its plugin which my plugin have no access to it, I am not sure how to proceed.

Thank you in advance.

I would also be interested in how to update a checklist custom field by a postfunction. All normal operations do not seem to work.
